Patent number: 7429737Abstract: A digital radiography (20) detector has a first housing (18) having substantially the form factor of a film cassette and having a chest wall edge (C). The first housing (18) has an X-ray converter (70) with a detection array (26), each detector generating a signal according to an amount of radiation received. Readout electronics (74) are coupled with switching elements in the detection array for obtaining the signals therefrom. The readout electronics (74) include elements formed from crystalline silicon and are distributed toward outer edges of the first housing (18) and away from the chest wall edge (C). X-ray shielding selectively protects the readout electronics (74) and is located beneath a portion of the detection array. A second housing (40), electrically connected to the first housing (18) has a power source for the detector, readout and control electronics for obtaining signals provided from the detection array (26).Type: GrantFiled: November 9, 2006Date of Patent: September 30, 2008Assignee: Carestream Health, Inc.Inventors: Timothy J.

Patent number: 6098264Abstract: A replaceable modular opto-mechanical unit includes a light source in the form of, for example, a laser assembly; an optical modulator assembly which modulates light from the light source; and a lens located in a light path between the light source and the optical modulator assembly. The lens focuses the light from said light source toward a center of the optical modulator assembly. The unit further includes a base adapted to removably support the light source, the optical modulator assembly and the lens in an optically aligned manner. The base is further adapted to be removably attached onto a receiving structure of a printer, such that an attachment of the base having the optically aligned light source, optical modulator assembly, and lens supported thereon, permits light from the optical modulator assembly to be focussed onto an optical element of the printer.Type: GrantFiled: February 17, 1999Date of Patent: August 8, 2000Assignee: Eastman Kodak CompanyInventors: Michael E.

Patent number: 5668899Abstract: Apparatus for coupling a radiation beam to an optical fiber includes an optical fiber holder, a housing, and a lens positioned in the housing. A flexure provides angular and longitudinal alignment of at least one of the lens and the optical fiber holder relative to the other of the lens and the optical fiber holder for thereby positioning and focusing of the beam on the radiation-receiving end of a received optical fiber. The flexure may be a thin, flat member with a first support region fixed relative to the lens and a second support region fixed relative to the fiber holder. The first and second support regions are circular and co-axial, and the second support region has diameter greater than the first region. The first and second support regions are connected by a plurality of flexible bridge pairs.Type: GrantFiled: April 24, 1996Date of Patent: September 16, 1997Assignee: Eastman Kodak CompanyInventor: Bradley S.

Patent number: 5529412Abstract: A print guide mechanism having parallel first and second guide rods, and a carriage assembly designed to move along the guide rods. The carriage assembly in a preferred embodiment comprises a frame and at least one pair of associated roller bearing assemblies being secured to the frame and being arranged so as to engage the first guide support rod for providing linear movement of the carriage assembly along the first guide rod, at least one upper roller bearing assembly mounted to the frame for engagement with the second guide rod, and a first mounting assembly having at least one lower roller bearing assembly. The at least one upper and lower roller bearing assemblies are arranged so as to engage the second guide rod between. The first mounting assembly is pivotally mounted to the frame so as to compensate for parallel misalignment between the guide rods and is biased for applying a loading force so that positive engagement is provided between the guide rods and the roller bearing assemblies.Type: GrantFiled: August 11, 1994Date of Patent: June 25, 1996Assignee: Eastman Kodak CompanyInventors: Bradley S.

Patent number: 5410338Abstract: A method and apparatus is disclosed for adapting a low precision lead screw to perform in a high precision application by compensating for cyclical positioning errors that are produced by the lead screw. A stage assembly driven by a stepper motor is individually characterized and its inherent cyclical positioning error is stored in a memory device. The memory device is used to control a driving circuit that controls an operation of the stepper motor. The stepper motor is driven in a non-uniform manner that is complementary to a pattern of cyclical positioning errors in the stage assembly. As a consequence, a stage, driven by the lead screw, moves in a uniform manner. The system is disclosed in the context of a printer in which a receiver is driven at a uniform rate by an inexpensive low precision lead screw.Type: GrantFiled: December 29, 1993Date of Patent: April 25, 1995Assignee: Eastman Kodak CompanyInventors: Bradley S. Jadrich, David K. McCauley
